I use Firefox on my Android phone & laptop. I have NoScripts on my laptop instead of AdBlock Plus. I like that I can customize it with the drop down list it gives of everything it blocks on every page. I can permanently block some things on every page and allow other things. Like I allow a couple things on the DIS so the smilies appear properly. But not any annoying popups or ads on the page. I couldn't figure out how to do that with AdBlock Plus.
On my phone I do have AdBlock installed. It works fine enough on my phone that I don't need the customization I do on my laptop. I don't visit as many sites on my phone, while out & about.
I also have Chrome installed on my Android phone. You CAN have more than one browser installed and running at the same time. Chrome usually comes pre-installed on Android phones as Google owns both. I just download the Firefox app from Google Play. Install AdBlock Plus and I'm good to go. I use Chrome for when I have to attach files to my Gmails. Firefox doesn't work as well for Gmail on my phone. Whereas, because Google also owns Gmail, they configured it so Chrome works better for it. For reading the Dis and other sites, I use Firefox.
